What Is Eco-Drive? This is the process that Citizen watches use to harness energy from any kind of light sources, whether artificial or natural. The energy is then stored in a rechargeable lithium-ion cell, that can be charged continuously and run forever. This watch is flawless and no dent not scratch at all, as good as brand new. Just only use in one event the reason I sell is that I’m no longer using it. الحالة جديد
